Abstract
A beam forming and adding unit receives an echo signal containing reflection by a side lobe of an ultrasonic pulse, and executes its focusing. A fundamental wave BPF unit and a fundamental wave detecting unit extract a fundamental wave component from the echo signal, and calculate its signal power. A harmonics BPF unit and a harmonics detecting unit extract a harmonics component from the echo signal, and calculate its signal power. A ratio calculating unit and a ratio comparing unit calculate a ratio of these two calculated signal powers, compare this power ratio with a power ratio threshold value stored in a reference memory, and notify its comparison result to a detection signal suppressing unit. The detection signal suppressing unit suppresses the echo signal according to the notification result, and outputs the echo signal. A display unit generates and displays an ultrasonic image based on the output echo signal.
